Safety Instructions For Oscillating Edge Belt/
Spindle Sander
Safety is a combination of common
sense, staying alert and knowing how
your oscillating edge belt/spindle
sander works. Read this manual to
understand this sander.
Safety Signal Words
DANGER: means if the safety infor-
mation is not followed someone will
be seriously injured or killed.
WARNING: means if the safety infor-
mation is not followed someone
could be seriously injured or killed.
CAUTION: means if the safety infor-
mation is not followed someone may
be injured.
Before Using The Sander
WARNING: Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals known
(to the State of California) to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
Lead from lead-based paints,
Crystalline silica from bricks and cement and other masonry prod-
ucts, and
Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
work in a well ventilated area, and work with approved safety equip-
ment, such as those dust masks that are specially designed to filter
out microscopic particles.
WARNING: To reduce the risk of
mistakes that could cause seri-
ous, permanent injury, do not
plug the sander in until the fol-
lowing steps are completed.
• Assembly. (See pages 12-19)
• Learn the use and function of the
ON-OFF switch. (See page 21)
• Review and understanding of all
safety instructions and operating
procedures in this manual.
• Review of the maintenance meth-
ods for this sander. (See page 29)

Safety Instructions for Oscillating Edge Belt/
Spindle Sander (continued)
Read the following WARNING labels found on the sander:
When Installing Or Moving The Sander
Avoid dangerous environment.
Use the sander in a dry, indoor place
protected from rain. Keep work area
well lighted.
To reduce the risk of burns or other
fire damage, never use the sander
near flammable liquids, vapors or
gasses.
To reduce the risk of injury or
death from electrical shock:
Ground the sander. This sander has
an approved 3-conductor cord and a
3-prong grounding type plug. Use
only 3-wire, grounded outlets rated
120 volts, 15 amperes (amps). The
green conductor in the cord is the
grounding wire. To reduce the risk of
electrocution, Never connect the
green wire to a live terminal.
Make sure your fingers do not touch
the plug’s metal prongs when plug-
ging or unplugging the sander.
• Never use this or any power sander
for wet sanding. Doing so could
cause electrocution, serious injury
or worse.
To reduce the risk of injury from
unexpected sander movement:
• Always unplug the sander before
moving it.
• Put the sander on a firm level sur-
face where there is plenty of room
for handling and properly supporting
the workpiece.
• Attach rubber feet.
• Support the sander so it does not
rock.
• Bolt the sander to its work surface.
Use the fasteners and method
shown in “Assembly.” (See page
16.)
Never stand on tool. Serious injury
could occur if the tool tips. Do not
store anything above or near the
tool where anyone might stand on
the tool to reach it.
5
Before Each Use
Inspect your sander. Check for:
• alignment of moving parts,
binding of moving parts,
• broken or damaged parts,
• work parts that cause a gap larger
than 1/16" between work support
and sanding surface,
sanding belt narrower than 4 inches.
Narrower belts uncover parts that
could trap your fingers,
• worn or damaged electric cords,
stable mounting, and
any other conditions that may affect
the way the sander works.
Remove adjusting keys and
wrenches. Form a habit of checking
for and removing keys and adjusting
wrenches from table top before turn-
ing sander on.
If any part is missing, bent, or broken
in any way, or any electrical parts
don’t work properly, turn the sander
off and unplug the sander. Replace
damaged, missing, or failed parts
before using the sander again.
Disconnect the sander to reduce
the risk of injury from accidental start-
ing. Turn switch off, unplug sander
and remove the switch key before
changing the setup or sanding drum.
Maintain tools with care. Keep the
sander clean for maximum and safest
performance.
To reduce the risk of injury from
jams, slips or thrown pieces:
Use only recommended accessories.
Use the correct spacer ring insert.
The opening between the sanding
sleeve and insert must be 5/32 of an
inch or less. (See page 15)
All sanding drums, washers and
knobs are tight. No parts should
have excessive play prior to operat-
ing unit.
Keep work area clean. Cluttered
work surfaces invite accidents. Floor
must be clean and dry for stable
footing.
Plan Ahead To Protect Your Eyes, Hands, Face and Ears
Dress for Safety
Any power sander can throw foreign
objects into the eyes. This can result
in permanent eye damage. Always
wear safety goggles, not glasses
complying with ANSI Z87.1 (or in
Canada CSA Z94.3-99) shown on
package. Everyday eyeglasses
have only impact resistant lenses.
They are not safety glasses. Safety
goggles are available at many local
retail stores. Glasses or goggles not
in compliance with ANSI or CSA
could seriously hurt you when they
break.
• Sanding operations are usually
dusty. Wear a dust mask along with
the safety goggles.
• Wear nonslip footwear.
• Tie back long hair.
• Roll long sleeves above the elbow.
• Noise levels vary widely. To reduce
the risk of possible hearing damage,
wear ear plugs or muffs when using
sander for hours at a time.

Safety Instructions for Oscillating Edge Belt/
Spindle Sander (continued)
Do not wear loose clothing, gloves,
neckties or jewelry (rings, wrist
watches). They can get caught and
draw you into moving parts.
Know your sander. Read and under-
stand the owner’s manual and labels
affixed to the tool. Learn its applica-
tion and limitations as well as the spe-
cific potential hazards.
Plan your work. Think through how
you will hold and maneuver the work-
piece against the sanding drum or
belt.
Use the right tool. Don’t force tool or
attachment to do a job it was not
designed to do.
To reduce the risk of injury from
accidental contact with moving
parts:
• Do not layout, assemble, or setup
work on the sander while any parts
are moving.
Reduce the risk of accidental
starting. Make sure switch is “OFF”
before plugging sander into a power
outlet.
Inspect your workpiece. Make sure
there are no nails or foreign objects in
the part of the workpiece to be
sanded.
Plan the way you will hold the work-
piece from start to finish. Reduce the
risk of awkward operations and hand
positions where a sudden slip could
cause finger or hand to move into a
sanding surface.
Don’t overreach. Maintain balance
and footing.
Keep face and body to one side.
Stay out of line of a possible throw-
back.
Plan your work to reduce the risk
of THROWBACKS - when the work-
piece catches the sanding drum
and is torn from your hands:
• Make sure there is no debris
between the workpiece and its sup-
ports.
• When sanding irregularly shaped
workpieces, plan your work support
so it will not slip and be pulled from
your hands.
• Use extra caution with large, very
small or awkward workpieces.
• Never use this tool to finish pieces
too small to hold by hand.
• Use extra supports (tables, saw
horses, blocks, etc.) for any work-
pieces large enough to tip when not
secured to the work surface.
Never use another person as a sub-
stitute for a table extension, or as
additional support for a workpiece
that is longer or wider that the basic
sander table, or to help feed, sup-
port or pull the workpiece.
• Sand only one workpiece at a time.
• Clear everything except the work-
piece and related support devices
off the table before turning the
sander on.
• Always feed workpiece from right to
left against the direction the sanding
sleeve or belt is rotating.
• Do not use drums, sanding sleeves
or sanding belts which show visual
signs of wear such as grooves,
tears or rips.
WARNING: Don’t let familiarity
(gained from frequent use of
your sander) cause a careless
mistake. A careless fraction of a
second is enough to cause a
severe injury.
7
When Sander is Running
Before starting your work, watch the
sander while it runs. If it makes an
unfamiliar noise or vibrates exces-
sively, Stop Immediately. Turn the
sander off. Unplug the sander. Do not
restart until identifying and correcting
the problem.
Never leave tool running unat-
tended.
Before using the sander, make sure
the sanding belt turns clockwise,
when viewed from above.
Keep children away. Keep all visi-
tors a safe distance from the sander
and workpiece.
Don’t force tool. It will perform better
and safer at its designed rate. Press
workpiece against the sanding sleeve
hard enough to begin sanding without
bogging down or binding spindle or
belt.
Before freeing any jammed mate-
rial:
• Turn switch “OFF”.
• Unplug the sander.
• Wait for all moving parts to stop.
Before Leaving The Sander
Turn switch off. Don’t leave tool until
the unit comes to a complete stop.
Make workshop child-proof.
Remove the yellow switch key. Store
it away from children and others not
qualified to use the tool. Disconnect
master switches. Lock the shop.
Precautions To Take When Sanding Metals
When sanding metals, sparks or hot
fragments could cause a fire. To
reduce the risk of this:
1. Disconnect any dust collecting
hose from the sander.
2. Remove all traces of wood dust
from inside the unit before sanding
metals.
3. Remove all traces of metal dust
from inside the unit before sanding
wood again.
Precautions To Take When Sanding Paint
Sanding of lead based paint is not
recommended. It is difficult to control
the contaminated dust that could
cause lead poisoning.
It is also difficult to identify whether or
not a paint contains lead. Therefore,
we recommend the following precau-
tions when sanding all paints:
1. Protect your lungs. Wear a dust
mask or respirator at all times.
Wear only dust masks that are suit-
able for working in lead paint sand-
ing environments. Ordinary
painting masks do not offer this
protection.
2. Do not allow children or pregnant
women to enter the work area until
paint sanding job is complete and
work area is clean.
3. To prevent ingesting contaminated
paint particles: Do not eat, drink, or
smoke in a work area where paint
is being sanded. After sanding
paint, wash and clean up before
eating, drinking or smoking. Do not
leave food, drinks, or tobacco prod-
ucts in the work area where dust
can settle on them.
8
Precautions To Take When Sanding Paint
(continued)
4. Protect the environment when
sanding paint. Use a dust collection
system if possible. Seal the work
area with plastic if necessary. Do
not track paint dust outside the
work area.
5. Thoroughly clean the work area
upon completion of paint sanding
project. If project lasts for an
extended period of time, clean
work area often. Items such as
sanding dust, vacuum filter bags,
plastic drop cloths, etc. should be
placed in a sealed container and
disposed of properly. Clean all
items exposed to sanding dust.
Motor Specifications and Electrical Requirements

formed by a qualified service
technician.
2. Do not use in rain or where
floor is wet.
This tool is intended for indoor
use only.
WARNING: Do not touch the ter-
minals of plug when installing or
removing the plug to or from the
outlet.
If power cord is worn or cut, or damaged
in any way, have it replaced immediately.

Information
NOTE: The plug supplied on your tool
may not fit into the outlet you are planning
to use. Your local electrical code may
require slightly different power cord plug
connections. If these differences exist
refer to and make the proper adjustments
per your local code before your tool is
plugged in and turned on.
In the event of a malfunction or break-
down, grounding provides a path of least
resistance for electric current to reduce
the risk of electric shock. This tool is
equipped with an electric cord having an
equipment grounding conductor and a
grounding plug, as shown. The plug must
be plugged into a matching outlet that is
properly installed and grounded in accor-
dance with all local codes and ordi-
nances.
Do not modify the plug provided. If it will
not fit the outlet, have the proper outlet
installed by a qualified electrician.
A temporary adapter may be used to con-
nect this plug to a 2-pole outlet, as shown,
if a properly grounded outlet is not avail-
able. This temporary adapter should be
used only until a properly grounded outlet
can be installed by a qualified electrician.
The green colored rigid ear, lug and the
like, extension from the adapter must be
connected to a permanent ground such
as a properly grounded outlet box.
Improper connection of the equipment
grounding conductor could result in a risk
of electric shock. The conductor with insu-
lation having an outer surface that is
green with or without yellow stripes is the
equipment grounding conductor. If repair
or replacement of the electric cord or plug
is necessary, do not connect the equip-
ment-grounding conductor to a live termi-
nal.
If the grounding instructions are not com-
pletely understood, or if you are in doubt
as to whether the tool is properly
grounded, check with a qualified electri-
cian or service personnel.
WARNING: If not properly
grounded, this tool can cause an
electrical shock, particularly
when used in damp locations, in
proximity to plumbing, or out of
doors. If an electrical shock
occurs there is the potential of a
secondary hazard, such as your
hands contacting the sanding
belt/spindle.
NOTE: The adapter illustrated is for use
only if you have a properly grounded 2-
prong outlet.
NOTE: In Canada the use of a temporary
adapter is not permitted by the Canadian
Electrical Code.

Motor Specifications and Electrical Requirements
(continued)
Motor Safety Protection
IMPORTANT: To reduce the risk of motor
damage, the motor should be blown out
or vacuumed frequently to keep sawdust
from interfering with normal motor ventila-
tion.
1. Connect this tool to a power source
with the appropriate voltage for your
model and a 15-amp branch circuit with
a 15-amp fuse or circuit breaker. Using
the wrong size fuse can damage the
motor.
2. If the motor won't start, turn off the
power switch immediately and unplug
the tool. Check the spindle to make
sure it turns freely. If the spindle is free,
try to start the motor again. If the motor
still does not start, refer to the "Trouble-
shooting” chart.
3. If the motor suddenly stalls while sand-
ing, turn off the power switch, unplug
the tool, and remove the workpiece
from the belt/drum. The motor may now
be restarted and the sanding finished.
4. Fuses may "blow" or circuit breakers
may trip frequently if:
a. Motor Is Overloaded-Overloading
can occur if you sand too rapidly or
make too many start/stops in a short
time.
b. Line voltages should not be more
than 10% above or below the name-
plate voltage. For heavy loads, how-
ever, the voltage at motor terminals
must equal the voltage specified for
your model.
5. Most motor troubles may be traced to
loose or incorrect connections, over-
load, low voltage (such as small size
wire in the supply circuit) or to overly
long supply circuit wire. Always check
the connections, the load and supply
circuit whenever motor doesn't work
well. Check wire sizes and extension
cord length with the Wire Size Chart.
Wire Sizes
NOTE: Make sure the proper extension
cord is used and is in good condition.
The use of any extension cord will cause
loss of power. To keep this to a minimum
and to prevent overheating and motor
burn-out, use the table shown to deter-
mine the minimum wire size (A.W.G.)
extension cord.
Use only 3-wire extension cords with 3-
prong grounding type plugs and 3-pole
receptacles.

Bolting Oscillating Edge Belt/
Spindle Sander To Workbench
If sander is to be used in a permanent
location, it should be fastened securely to
a firm supporting surface such as a work-
bench, with either bolts or drywall screws.
Fastening with bolts
1.Use 1/4" bolts, washers, and nuts (not
included). The bolt length should be
1-1/2" plus the thickness of the work-
bench.
2. Locate and mark the holes where the
sander is to be mounted.
3. Drill (4) 3/8" diameter holes through
workbench.
4. Place sander on workbench, aligning
holes in base with holes drilled in work-
bench.
5. Insert (4) 1/4" diameter bolts and wash-
ers and attach nuts securely.
Fastening with screws
Drive (4) 2-1/2" long screws through the
holes in the base and through the work-
bench. Do not overtighten the screws.
CAUTION: To reduce the risk of
injury from tool movement, use
either 1/4" diameter screws and
nuts or 2-1/2" long screws.
Clamping Oscillating Edge Belt/Spin-
dle Sander To Workbench
An alternative method of mounting is to
fasten the sander to a mounting board.
The board should be sufficient size to
avoid tipping while in use. Any good
grade of plywood or chipboard with a 3/4"
thickness is recommended. (Thinner chip-
board can break.)
NOTE: For proper stability, holes must be
countersunk so screw heads are flush
with the surface of supporting board.

Removing/Installing the Sanding
Belt
Tensioning and Tracking
WARNING: To reduce the risk of
injury from accidental start, make
sure tool is unplugged before
removing or installing sanding
belt.
Some sanding belts have a “directional
arrow” on the inside or smooth side. If
there is an arrow, the belt must run in the
direction of the arrow so the splice will not
come apart. If there is no arrow the belt
may be put on either direction.
1. Slide the tension lever to the left to
release the belt tension.
2. Remove the sanding belt.
3. Place the replacement sanding belt
over the drums as shown. Make sure
the belt is centered on both drums.
4. Slide the tension lever to the right to
apply belt tension.
5. Plug in the power cord. Insert the yel-
low switch key and turn the unit “ON”
and immediately “OFF”, noting if the
belt tends to slide off the drums. If it did
not tend to slide off, it is tracking prop-
erly.
6. If the sanding belt runs down towards
the table, turn the tracking knob clock-
wise 1/4 turn.
7. If the sanding belt, runs up away from
the table, turn the tracking knob coun-
terclockwise 1/4 turn.
8. Turn switch ON” and immediately
“OFF” again, noting belt movement.
Readjust tracking knob if necessary.
